I hate to break it to you, but those two missions are pretty much impossible to finish all the way. First few stages might be doable though. Calculations showed me that you would need to farm aakas 1 (cheapest options) for 10 hours a days (20 runs on a 30min/run average) for 4 years straight. If I were you, do it as a side-goal passed stage 1 and hope the missions are going to be updated in the future. And as always, love to read your blog.
